M.Y. won an award on the 5th Ensemble Workshop for Young Researchers held at Tohoku University on 7th June 2019 with the title of "Molecular Engineering Approach towards the Understanding and the Functionalization of Carbon Materials."




Sho-rei Award











M.Y. had a lecture at the Research Center for Solar Energy Chemistry (Osaka University) regarding molecule-based artificial photosynthetic systems as well as the recent progress in carbon-based catalysis for the chemical conversion reactions. For details: the Research Center for Solar Energy Chemistry (Osaka University)








Porous Carbon



A scientific paper is accepted by Nature Communications: Nano-confined spaces in porous carbon materials enable anomalous phenomena, and we reported herein the complusive gas-liquid phase transition mediated by flexible porous materials.












Analytical Chemistry



A scientific paper regarding analytical chemistry is published in ChemPlusChem. The paper describes the factors governing intermolecular interactions at solid-liquid interfaces: Typically, the interactions at molecular level can be understood and controlled in terms of various interactions including π‒π interactions and hydrogen bondings. Instead, this research reveals another factor, the entropic term in relation to the dynamics of solid phases, for controlling the interactions using various spectroscopic analysis. Such a new understanding of interactions at the solid-liquid interfaces is of particular interest in relation to the development of analytical method and understanding of enzymatic reactions in biology.

Tohoku University



Dr. M. Yamamoto has joined the Institute of Multidisciplinary Research for Advanced Materials at Tohoku University as an Assistant Professor.


When we achieve carbon materials with the well-defined structures that could be well-documented at the molecular level, many interesting physicochemical properties will also be expected in the fields ranging from the electrochemistry and catalysis to force-induced gas-liquid phase transition as has been reported by us (Nat. Commun. 2019, in press). The design, synthesis, and investigation of such a facinating carbon material (chemistry of carbon) are ongoing at Tohoku University. The details shall be disclosed in due course.

Artificial Photosynthesis



The collaborative work with Prof. L. Hammarström is published in Angewandte Chemie International Edition. The paper reports a single-molecule-based artificial photosynthetic system for visible-light-driven water oxidation, and the photochemical properties were corroborated by the photophysical analysis using femtoseccond and nanosecond laser transient absorption spectroscopy.
